How stainless steel insulated water tank can achieve its more energy-saving effect:
Insulation for pipelines and water tanks. Pipeline insulation includes insulation for circulation pipes, hot water supply pipes, and return pipes. The insulation of water pipes can be done with insulation cotton or polyurethane foam. Small pipes are generally insulated with insulation cotton, while large pipes are insulated with polyurethane foam. When the ambient temperature is low, the water temperature drops significantly. If the supply water pipe is equipped with a return water system without insulation for the heating and return pipes, the wasted heat will increase significantly and the energy efficiency ratio will sharply decrease. The insulation of the water tank is equally important. Stainless steel insulated water tanks are generally insulated with a 5mm polyurethane foam insulation layer, and then a layer of stainless steel is added outside the insulation layer. This way, the insulation effect of the water tank is good.
The installation method in engineering can also affect the energy-saving effect of the heat pump. It can be divided into two modes based on different usage methods: all-weather water supply and timed water supply: all-weather water supply is mainly used in hotels, restaurants, hospitals and other places, while timed water supply is mainly used in schools, factories and other places.
The installation method for timed water supply is relatively simple. Just install two circulation pipes on the water tank and the main unit for circulating heating, and then refill the hot water with cold water after a certain period of time to reheat it. This installation method is very energy-efficient.
There are many installation methods for all-weather water supply, such as direct heating, circulation, large and small water tank modes, and so on.
Direct heating refers to the use of hot water directly from cold water heated by the main unit, and the outlet temperature can reach between 45-55 ℃. This principle is controlled by a throttling device to regulate the amount of water replenishment. The water flow cannot fill the entire heat exchanger, so when making a direct heating host, it is necessary to consider that the diameter of the heat exchanger cannot be too large, and the most reasonable diameter and water flow method should be selected through repeated debugging.
Circulating heating is a method in which the host heats up the water in the water tank through circulating heating. When a portion of the water in the tank is used up, it replenishes the tank and then recirculates it to the desired temperature. This installation method is relatively simple.
The large and small water tank mode refers to the host first heating a small water tank to a certain temperature, then supplying all the water in the small water tank to the large water tank, and then heating the small water tank with supplementary cold water, continuously circulating until the large water tank is filled with hot water. This approach is relatively complex in terms of control, but does not involve the phenomenon of the host basically heating at high temperatures like the circulating heating. Therefore, the energy-saving effect is relatively high.
